Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
The last day of the specified month is the "0th" day of the next month. FileMaker performs the math. This function will work for any month (including December), and will handle leap years just fine.

I had trouble wrapping my brain around this and had to try this in a test database to see how it actually worked.
A supplied date of 12/15/2000 would evaluate to "13/0/2000", and FileMaker does the math, properly returning "12/31/2000".
Nice, simple function!
